BUCKLING Erm-GATE Fon wAGoNs.

SPECIFICATION fqrming para of Leners Patent No.' 768,739, dated August so, 1904 application sied my 17, 1904.

' boxes; and to such end it consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

rIhe invention is illustrated in the accompanying drawings, wherein like characters indicatelike parts throughout the severeiews. Figure lis a perspective view showing a portion of a wagon-box having one of cfnr improved buckling end-boards appliedthereto. Fig. 2 is a plan view of the parts shown in Fig. 1. Fig. 3 is a vertical section through the end-board on the line tra .r3 of F ig- EL, and Fig. 4 is a horizontal section on the line .'c .fc of Fig. 3.. 'The numeral 1 indicatcs'a wagon-box having at one en d the usual verticallydsposed gate-retainingocleats 2 rigidly secured to its sides.

The'numeral 3 indicates the usual tie-rod, which is extended transversely through the Sides of the box inward of the seats formed for the ends of the gate between the cieats 2. The numeral 4 indicates the'relativey long section, and the numeral 5 the r'elativei short section, of the buckling end-gate, which sections arc connected by hinges, which adapt the gate to buckle outward. One of the gatesections, and as shown and preferred the short section 5, has a rigidLv-secured lock-beard 7, which overlaps the section 4 and es'ends nearly but notquite to the'end thereof- This lock-board has near its free end a longitudinelly-extended slot 6 and is also provided with a metallic plate 9, which plate has a slot registering with the said slot 8 and is formed at Serial No. 208,379. (No model.)

its intermediate portion with lock-depressie 10, that extend transverselyl of the sain slot -A lock, which also serves as 'the handpie( is swiveled to the gate-section 4 in a positi to be passed through the slot 8 and throu; the slot of the plate 9. This combined lo and handpiece is preferablygin the form of stern or bolt 11, having atits outer end a lo 12. Said stem is passed through the ga' section 4 and, as shown, also through a wash 13, placed against thesaid section, and is p1 vided at its outer end with a nut 14. A coil spring lsurrounds the stem 11 and is'co; pressed between the nut 14 and the Washer] A cap 16, secured to 'the gate-section 4, i closes the spring 15 and the nut 14 and t end of the stem 11. Preferably the end said stem 1l is upset to prevent the nut from Working off from the same. The he of the cap 16 adords a stop to limit the moi ment of4 the stem l1 under the action of t spring 15. f

When the head 1.2 of the stem 11 is turn i'nto line with the slot 8, it may be pass throughsaid slot and through the slott plate 9 to thereby force the lock-board against the gate-section 4. Then by drawi; outward on the said head it may be mov clear of the said plate and turned into t lock-depressions 10, in which position it w be held against accidental .displacement the spring 15. f A

17V-hen the'sections of the gate are locked straight line with each other, as justdescribe the gate is of course in' condition for u: Then it is desired to trip the gate and all( the same to buckle, the head or handpiece is drawn outward so as to clear the plate and is then turned into line with the slot said plate and allowed to fall into the slot thereby nermitting the end-gate to buckle, indicated by dotted lines in Fig. 2.

rIfhe Well-known purpose of a buckling gz of this character is to permit the gate to easily removed from working positionfivh` lit is under pressure from a load contain within the wagon-box. i

The device described wh-ile extremely si ple and .of small cost is e'icient for the pun: poses had in View and may beeasly and quickly manipulated. Furthermore, there is no danger of the said device becoming accidentally unlocked. lt will be understood that the device described is capable of moditions within the scope of our invention as herein set forth and claimed. n

What we claim, and d esire to secure byLetters Patent of the United States, is as follows:

1. In a buckling end-gate, the combination` with gate-sections hinged together, th'e one having a projecting lock-board, slotted at its free end, of a spring#pre&sed lock pivoted to the other gate-section and havinga head adapted to be passed through the slot of said iock board and' interlocking therewith under the action of its spring, and turned transversely thereof, to lock the gatesection's against buckling movements, substantially' asdescribed.

2. In a buckling end-gatevthe combination y vith gate-sections hinged together, the one having a. projecting lock-baard formed wi'th slotand with transverse lk-d'epressions, and

theothergate-,seetion having a swivel, spring pressed lock, the head of which is'insertibh through the slot of said lock-board and i: adapted to be? turned into engagement Witl the lock-depressions thereof, substantiallya.' described. k

3. The combinations with the gate-section: 4 and 5, connected by hinges 6, o'f the lonkboard 7, rigidly secured to said section 5,1m:4 having lat its free end' the slot 8 andLsiotte plate 9,' the latter having lockfdepressons 10.

and the Ispri11g-pressed stem'll swiveled t( said section 4 and having thehead 12, adapte(l to be passed through seid slot-8 and the slot of said plate 9, and to be turned into engagement with said lock-depressions 10, substantially as described..

In testimony whereof we atlix our signatures in vpresence'of two witnesses.v BERNARD A. FAUST.
